HOOK.

Application filed April 23, 1924. ficrial No. 708,397.

of Bay and State o'l Michigan, have invented certain newand usefulImprove ments in Hooks, of which the following is a specification.

This invention relates to hook supports and the like, and particularlyto a hook for use in supporting forms from beams, girders, or otherstructural members, and into which concrete is poured.

()ne object of the invention is to design a very simple, and substantialhook for supporting forms and the like from steel work, and which canalso be used for hanging and supporting a monorail system, mechanicalequipment, piping, permanent or temporary balcony, or in fact anyweight. or object which it is desired to suspend from a beam or ceiling.

Another object is to provide a form support from which the bolts can beremoved after the concrete is set, so that a clean opening remains whichcan be neatly and easily pointed up, and which leaves no exposedmetalparts to form'rust spots, etc.

A further object is to provide form supports adapted to engage theflanges of the structural members, one on each side, and means wherebythey can be tied together to prevent displacement due to a suspendedweight or when the concrete is being poured.

lVith the above and other objects in View, the present inventionconsists in the combination and arrangement of parts, hereinafter morefully described, illustrated in the accompanying drawings, andparticular ly pointed out in the appended claims, it being understoodthat changes may be made in the form, sizes, proportion and minordetails of construction without departing from the spirit, orsacrificing any of the advantages of the invention.

In the drawings:

Fig. 1 is a side view otmy improved hook showing a bolt in positiontherein.

Fig. 2 is an edge view thereof.

Fig. 3 is a central vertical sectional view of the hanger only. i

Fig. 4: is a top plan view thereo'hand Fig. 5 is a bottom view.

Fig. 6 is a vertical cross "iew 01" a large standard I-beam,illustrating the hooks used for supporting a form for concrete work.

Fig. 7 is'a view showin the hooks proper in place on a small I-beam castin the concrete, another pair othooks being placed on the lower end ofthe bolts, and engaging an I-beam serving as a part oi a monorailsystem.

Fig. 8 is a view similar to Fig. 6 show ing a section of I-beam with anextra heavy flange, the hooks supporting a pipe and a balcony.

In construction work in general itis customary to use shoring to supportthe forms into which the concrete is poured, this is both expensive andinconvenient, as the shores must; be very numerous and considerablewedging must be done to make the job accurate and true, and these shoresohstruct and hinder the workman and mustremain in position until theconcrete is set, also, the shoringmust be cut to predetermined lengths,and when once used, may not lit the next job, further, when the concreteis set, there is no "opening or attaching means for simporting any,mechanical equipment, unless especially provided for,

these disagreeable features it have overcome in my improved constructionwhich leaves a tree clear space, automatically provides supports andleaves a smooth finished job, as the entire dead load is on the beamwhile where the concrete is green and little or no deflection occursafter the con' crete is set. v

Referring now particularly to the drawings in which I have shown thepreferred embodiment of my invention, the numeral 5 indicates the hookor support, which is formed as clearly shown in Figs. 1, 2 and 3 of thedrawings, being provided with jaws 6 adapted to engage the flange of anI--bea1n or other structural member, the head 6 being rounded and isformed with spaced apart ribs 7, adapted to receive a nut 8 betweenthem, a vertically disposed opening 9 extends through this head andspaced apart hook shaped legs 10 are formed integral therewith,extending downwardly and converging at their lower ends.

It will be noted that the shape of the member is such that when it is inengagement with the flange or other structural member it will have a twopoint bearing thereon. the jaw engaging the upper surface, while thelower end enga the under side of the beam, the bolt 12 euendingsphstantially vertical. In form work these llt) supports are used inpairs and numerous enough to support the form and are adapted to beconnected by means of a strand of wire 13 passed around the roundedsection 14 between the legs and then twisted tight as shown, thisprovides a very sim ple and economical. method of fastening, and anywidth or section of beam can be accommodated.

I wish to direct attention to the tact that the hook is appliable to anybeam or girder, and in Figs. 6, 7 and S I have illustrated a large,small, and thick girder, and it will be obvious that the hook willassume slightly different positions, when applied to tl ese differentsized and proportioned members, the opening 9 is therefor made large andthe head rounded so that proper bearing may be provided for the bolt nutin any required position, these ribs being spaced to allow the nut torest therebetween, the adjusting being accomplished by turning the headof the bolt, this makes an ideal adjustment and eliminates the wedgesand blocks together with the labor and material involved in the shapingthereof.

In Figure 6 I have shown a sectional tragmentary view of a form l t intowhich concrete is poured, this form being supported by the hooks securedtogether by the strands of wire which are twisted until proper tensionis secured. The bolts 12 first greased and then inserted through thesoliit planks 15, bed blocks 16, and washer 17 Pairs of these supportsare spaced along the beam at predetermined distances and a block ofproper thickness is then inserted between the underside of the beam andthe form, and each pair of bolts adjusted by means of a wrench appliedto the head thereo't, when the adjustment is completed the concrete ispoured into the term, and when set, the wrench is again applied to theheads of the bolts and they are then backed out of the form to be againused, or can be reinserted in position for supporting mechanicalequipment, pipes, balconies, etc., as indicated in Figs. 7 and S, thesupports proper, together with the nut remaining in the concrete and inengagement with the beam.

In Fig. 7 the supports are shown set in the concrete, and again assume adifferent angle due to the size of the beam, the bolt bearing and pointsof contact with the beam are howeier always the same, the opening androunded head permitting the bolt to be accommodated at these variousangles, in this instance an Z-eam is suspended from a second pair ofsupports secured on the lower ends of the bolts. and this E-beam can beused as a monorail system or the like.

Fig. 8 illustrates the hanging of pipe lines, and the hook used as asupport tor a balcony.

From the foregoing description it will be obvious that I have perfecteda very simple, substantial and economical hook for attaching to theflanges of the I-beams or other structural members for supporting forms,mechanical equipment, and various members therefrom.

What I claim is l. A hook adapted to engage the flange oil? a structuralmember and having a two point contact therewith, a head on the hookadapted to engage the inside ot the flange ot the structural member, avertically disposed opening through the head and a bolt removablymounted therein.

2. A hook provided with a jaw and adapted to engage the flange of astructural memher and formed with a curved head, spaced apart legsformed integral therewith and engaging the bottom ot the structuralmember, and an opening through the head adapted to accommodate a bolt atvarious angles.

3. A hook formed with a jaw adapted to engage the flange of a structuralmember and having a curved head formed with spaced apart raised ribsadapted to receive a nut between them, and a pair of legs depending fromsaid head and adapted to engage the underside of the structural member.

l. A hook support formed with a jaw adapted to engage the flange of astr ctural member, and having a curved head formed with spaced apartribs adapted to receive a nut between them, legs depending from andformed integral with the head, and adapted to engage the underside ofthe structural member, and an opening through the head adapted toaccommodate a bolt at various angles.

5. A hook support formed with. a jaw adapted to engage the flange ot astructural member, and having a curved head "formed with spaced apartribs legs depending from said head and adapted to engage the undersideof the structural member, and a rounded connecting wall connecting saidlegs.

6. The combination with a structural member, of a pair or" hooks adaptedto engage opposite edges thereof, said hooks being formed with curvedheads having legs depending 'heretrom, and flexible means for securingthe hooks together.

7. The combination with a striu-tural member, out a pair of supportsadapted to engage opposite sides thereof, said hooks being formed with ajaw and a curved head, legs depending from the head and connectedtogether at their lower end, a vertically disposed opening through thehead and adapted to receive a. bolt and flexible means for seeming thehooks together.

8. The combination with a structural member, of a pair of hooks adaptedto enopposite sides thereof. said hooks haw ing jaws, a curved headhaving spaced apart ribs thereon, spaced apart legs depending from saidhead and engaging the underside of the structural member, oonneetingWall between the legs, and flexible means engaging said Walls for tyingthe hooks together.

9. The combination with a supporting member, of a pair of hooks adaptedto e11- gage the opposite sides thereof, said hooks being formed Withcurved heads terminating in a jaw, an opening through said head, spacedapart legs depending therefrom, a 10 Wall connecting the legs togetherat the free ends thereof, and flexible means for engaging said Wall forsecuring the hooks together.
